Abstract

A single-use syringe for injections comprises a cylindrical casing (1) and a piston (2) and a rod (3) mounted inside it. The rod (3) has a profiled configuration and consists of a plurality of truncated cones (7) assembled consecutively along its length, and a hollow profiled insertion (8) consisting of two parts (8a, 8b) is mounted coaxially to the rod, the internal surface of the insertion corresponding to the external surface of the rod (3) and the external one being formed by the surfaces of a plurality of truncated cones (9). Between the piston (2) and the insertion (8) is mounted coaxially to the rod (3) a washer (10) with an inclined lateral surface, whereas the internal surface of the casing (1) is provided with an annular protrusion (11) one of the surfaces of which is inclined and corresponds to the inclined surface of the washer (10). The single-use syringe may be utilised in any medical establishments and is suitable for individual use.
